I came from a primary school where caning is just given even so frequently. I have been caned because of forgetting to do my homework, not bringing textbooks, failing spelling tests and so on. I was particularly naughty when I was in primary 2 and 3, so that was when I received most of my caning (could recall about 5 incidents at least which I was caned).
Most of the time before the caning, I would have known that I will be caned. The time waiting is scary indeed. She will then take the cane, hit the cane against the desk a few times, before calling the poor names to be caned. Sometimes she calls them out one by one, sometimes all those who will be caned line up first before receiving the strokes.
